You could try with something like the following (just came up with it) inside your main module's run() block:
app.run(function($route, $rootScope)
{
$rootScope.path = function(controller, params)
{
// Iterate over all available routes
for(var path in $route.routes)
{
var pathController = $route.routes[path].controller;
if(pathController == controller) // Route found
{
var result = path;
// Construct the path with given parameters in it
for(var param in params)
{
result = result.replace(':' + param, params[param]);
}
return result;
}
}
// No such controller in route definitions
return undefined;
};
});
This will extend the root scope of the application with the new path() function - so it can be used anywhere in the application. It uses the $route service to get the controller names and the corresponding paths, so you won't have to repeat yourself.
Example usage:
{{ path('LibraryController', { bookId : 'x', chapterId : 'y' }) }}
